Error unrecognised arguments

[emilywilson2]

After creating the looker.ini file in this format:

[Looker]
# Base URL for API. Do not include /api/* in the url
base_url=https://myinstance.eu.looker.com:19999
# API 3 client id
client_id=123456789
# API 3 client secret
client_secret=123456789
# Set to false if testing locally against self-signed certs. Otherwise leave True
verify_ssl=True

[Production]
base_url=https://myinstance.eu.looker.com:19999
client_id=123456789
client_secret=123456789
verify_ssl=True

and running the command henry pulse --config-file=looker.ini --section=Looker

i get the error: unrecognized arguments: --config-file=looker.ini --section=Looker

i believe i am in the right directory, as shown by the screenshot here after the ls command

could anyone help with this?
